Long-period gratings in chalcogenide fibers

, 2010
Les verres chalcogénures sont des matériaux optiques connus depuis 50 ans. Ils sont fortement non-linéaires, transparents dans l'infrarouge et photosensibles à la lumière visible. Grâce à des percées récentes du côté des procédés de fabrication, leurs applications dans divers domaines sont devenus possibles, notamment dans les capteurs biochimiques, le
